Scan Tool Setup and Functionality: Notes

Connect the scan tool to the data link connector (DLC) for communication with the vehicle.

The DLC is located in the drivers side compartment. It is attached to the instrument panel under the steering column and accessible from the driver seat.

The DLC is rectangular in design and capable of accommodating up to 16 terminals. The connector has keying features to allow easy connection.

The required scan tool functions are described below:

• monitor, record, and playback of parameter identification (PID)s
• freeze frame PID data
• diagnostic test modes; self-test, clear diagnostic trouble codes (DTCs)
• output test mode
• resetting keep alive memory (KAM)
• diagnostic monitoring test results (mode 6) for on board diagnostic (OBD) on board monitors
• on board system readiness (OBD monitor completion status)

Some of these functions are described in this part. Refer to the scan tool manufacturer's article for specific information on the scan tool setup, operation, and specific cables and adapters required.
